[0002] Nowadays, with the rapid development of logistics industry, electric roller sorting machine as an important logistics equipment has been widely used in automatic sorting, conveying and other links. This equipment drives the conveying belt through electric roller to carry out automatic sorting and transportation of goods. The efficient operation of electric roller is crucial to improve logistics efficiency. However, in the process of long-term high-load operation, the wear and tear problem of electric roller surface gradually highlights, which becomes one of the important factors restricting the long-term stable operation of the equipment.

[0003] Due to the long-term high-load and high-frequency operation of electric roller, the wear and tear of roller surface will gradually increase, resulting in the decrease of operation efficiency and reliability of the equipment. This wear and tear not only affects the service life of the roller itself, but also causes different degrees of damage to the conveying belt, roller bearing and other components used in cooperation, increasing the cost of maintenance and replacement. More seriously, with the aggravation of wear and tear, electric roller will produce a lot of noise during operation, affecting the comfort of working environment and possibly interfering with the surrounding equipment.

[0004] At present, common electric roller surface treatment technologies include coating, electroplating and other means. Although these methods can reduce wear and tear to some extent, their effect is limited, and wear and tear will still occur after a long time of operation. In addition, there are some wear-resistant materials on the market, such as ceramic coating and high polymer composite material. However, due to the high cost and complex processing technology of these materials, they have not been widely used, and cannot meet the demand of large-scale application. The limitations of these technologies have restricted the performance improvement of electric roller sorting machine.

[0005] Therefore, how to reduce wear and tear, reduce noise, prolong service life and reduce cost on the basis of ensuring the performance of electric roller sorting machine has become an important direction of current technical improvement. The improvement and optimization of electric roller sorting machine, especially the breakthrough in wear resistance, noise control and cost control, have important technical value and market prospect.
